The experiment was performed at Agricultural Research Center in Jousiyet
Al-Kharab in Al-Qsair district, Homs governorate during the 2010-2011 season
to investigate the effect of planting depth and organic acids on saffron growth
and productivity.
Four treatments including amino acids, amino Humic,
mixture of them in addition to the control were applied. Each treatment was
comprised of three planting depths (10, 15 and 20 cm). Results showed that by
increasing planting depth up to 20 cm a significant reduction had resulted in
the percentage of rooted plants and number of shoots while there were no
significant differences between the two depths 10 vs. 15 cm. The number of
leaves and their length were not affected significantly with the increasing of
planting depths. The number of flower, wet and dry weights of the stigmas
were increased significantly with the increase of planting depth from 10 to
15 cm. The application of the humic acids had significant superiority overall
the other applications in rooted plant percentage, number of shoots, number of
flowers and the dry and wet weights of the stigmas, while the application of the
mixture came in the second rank in number of flowers and the dry and wet
weights of the stigmas. However, no significant differences were occurred
between the control and application of amino acids. The highest percentage of
rooted plants was observed in applying humic acids in all depths and the
percentage of rooted plants reached 100%. The highest number of flowers,
highest stigmas wet and dry weights were observed with the interaction
between applying humic acids at 15 cm depth. The highest number of shoots
and number of leaves appeared with the interaction between 20 cm depth and
humic acids treatment, the longist leaves were appeared with the interaction
between amino acids and 15 cm depth.

The effect of different culture medias (water, MS solid, MS 1/2 solid) on germination
and growth of heliotropiun hirsutissimum Grauer. in vitro was studied with different
concentrations of gibberellic acid (0.001-0.01-0.1 and 1 mg/l).
The results
showed that best germination rate (80.5%) and root (20mm) and shoot
(35mm) growth were obtained in MS solid medium with 0.1mg/l GA3.
Addition of 0.1mg/l GA3 to MS1/2 solid medium improved germination rate
(75.44%), root (19mm), and shoot (24mm)growth.
When GA3 (0.1 mg/l) was added to water medium, germination rate reached
(65.33%), as well as root and shoot growth (12.66mm and20mm) alternatively after 2
weeks of planting.
Seedling of MS solid medium were transferred into pots contained torp medium to
adapting them with outside environment, and then surviving their growth until maturity
after 4 weeks.
This research work aimed to study the effect of different mixtures of growing media
on pepper seedlings and their ability to withstand transplanting shock.The variety QarnAlgazal
of pepper and five mixtures of growing media were used.The mixtures i
ncluded bitmoss
alone,bitmoss with equal volume of soil or sand,soil and cow manure in a ratio of
1:2,and cow manure with soil and sand in a ratio of 1:1:1.
The experiments were implemented in aplastic green house without heating in the
nursery farm of the faculty of Agriculture,Tishreen University.The completely randomizel
design was adopted with three replications for each treatment and 15 plants for each replication.
The results showed that themedia containing cow manurewere the more effective ingrowth
of sapling as represteded by the increased hieght of sapling, number and area of
leafs,fresh weight of both biomass and roots of sapling.The effect was very clear in the
media containing cow manure and soil in the ratio of 1:2.
